abstract = {To understand how cells communicate in the nervous system,
it is essential to define their secretome, which is
challenging for primary cells because of large cell numbers
being required. Here, we miniaturized secretome analysis by
developing the 'high-performance secretome protein
enrichment with click sugars' (hiSPECS) method. To
demonstrate its broad utility, hiSPECS was used to identify
the secretory response of brain slices upon LPS-induced
neuroinflammation and to establish the cell type-resolved
mouse brain secretome resource using primary astrocytes,
microglia, neurons, and oligodendrocytes. This resource
allowed mapping the cellular origin of CSF proteins and
revealed that an unexpectedly high number of secreted
proteins in vitro and in vivo are proteolytically cleaved
membrane protein ectodomains. Two examples are neuronally
secreted ADAM22 and CD200, which we identified as substrates
of the Alzheimer-linked protease BACE1. hiSPECS and the
brain secretome resource can be widely exploited to
systematically study protein secretion and brain function
and to identify cell type-specific biomarkers for CNS
diseases.},
